Packet Tracer - Network Representation (Instructor Version) Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only. All clients have full connectivity to the servers. For the sake of frame diversity, the environment is not entirely realistic. For instance:



NAT and PAT overload are both being used on the Branch network, but the Central 10.X.X.X network is being shared publicly.



There is a separate DNS server in the 172 network due to the inability of computers to use the file server's public address. The simulated DNS server, unlike BIND, is basic and does not forward requests that it does not know to a root server - so the A records are duplicated.



EIGRP is running in the cloud, as opposed to BGP.



The Branch switch is actually providing DHCP, just because it can. It makes that side of the simulation different than the Central side.



The cloud includes two servers, one of which uses the correct IP of netacad.com, and the other uses the correct IP of Google's DNS.



The router passwords are "cisco" and "class", but there is a "banner motd" and "banner login" which readily give the passwords to the curious.



The S1 and S2 switches have spanning tree PVST enabled. Each has a different blocking port, so all connections are green.

Packet Tracer - Network Representation

Part 1: Overview of the Packet Tracer Program
The network size is larger than most of the networks you will experience in this course (although you will see this topology often in your Networking Academy studies). You may need to adjust the window size of Packet Tracer to see the full network. If necessary, you can use the zoom in and out tools to adjust the size of the Packet Tracer window.

Step 1: Access the Packet Tracer Help pages, tutorial videos, and online resources a. Access the Packet Tracer Help pages in two ways:
1) Click the question mark icon in the top, right-hand corner of the menu toolbar. 2) Click the Help menu, and then choose Contents.
b. Access the Packet Tracer tutorial videos by clicking Help > Tutorials. These videos are a visual demonstration of the information...
